Choosing the right distance between your projector and screen is essential to ensure you get the best possible image. You should set the distance based on your screen size and projector type, but if you get it just right you can enjoy a fantastic cinema-like movie and TV viewing experience at home.

Because every projector is different, and every projector user has a different screen size, the exact distance for your setup will likely be very different than someone else’s. If you have a short-throw projector, you may only be able to place your projector a few feet from the screen, while someone with a more traditional ceiling projector may need to place it ten or more feet from the screen.
The best place to find out what distance to set your projector is to look in the manual or on the manufacturer’s website. They will have specific instructions for your particular projector on how to set it to the perfect distance. This is especially important if you are using a short throw projector or mounting the projector somewhere that requires vertical or horizontal lens shift or keystone correction to make the image appear as if the projector is centered on the screen.
Keep in mind that projectors often have a minimum and maximum distance that you need to set from the screen to ensure that they can cover the entire screen or not go over the outer boundaries. You may still need to make adjustments to the image from your projector after you have set it up.
